The main objective of root-canal filling is to prevent bacterial colonization of tissue fluids and avoid survival and multiplication of bacteria remaining even after the most careful sterilization procedures. The level at which the root-canal filling must stop is controversial. The most agreed level is at dentino-cemental junction or what is known as apical constriction. But even though it is desirable to stop the obturation at apical constriction, in practice, however, it is practically not always possible. This is due to the fact that its ‘location is very variable. Often the constriction, felt by the tactile sensation can be deceptive. It could be due to presence of calcification, remote from the actual dentino cemental junction. Therefore, it is felt that radiographic terminus of the canal should be used as reference point to determine the canal length, even if it sometimes (it is an exception, not the rule) leads to a filling that protrudes beyond the foramen by fractions of a milimeter.
